Just remember if u want decent fps with a gts, a rez of 16x12 WILL cause issues.
I managed to find a samsung 20" with 14x10, which is about the most my sys will handle.
Wow.. If thats the highest rez your system can handle you may have a problem. Im still using an x850xt with e6600 at 1920*1200. Not the smartest combo, but it gets the job done just fine.
